The Cowes Power Station (also known as Kingston Power Station) is a 140 MW open-cycle gas turbine plant located in East Cowes on the Isle of Wight. Built in 1982 at a cost of £30 million, it remains the island’s only conventional power source, supplementing electricity imported from the mainland. The station is owned and operated by RWE Generation UK.

It consists of two 70 MW gas turbine units running on light fuel oil, used mainly during peak demand or for grid frequency support. When operating at full output, the turbines produce around 200,000 horsepower and consume 762 litres of fuel per minute. The plant can be controlled locally or remotely from the Hythe Power Station dispatch desk.

Cowes replaced an earlier 24 MW coal-fired station, decommissioned in 1976. The island’s grid is also connected to the mainland via 132 kV subsea cables, first installed in 1947, with later upgrades in 1964 and 1972, ensuring stable power supply for the Isle of Wight.
